Abstract (en)

[origin: EP0777388A2] An encoder, which encodes blocks of picture data of an input signal on the basis of motion detected between a block of the picture data and a corresponding block of stored reference picture data, having a noise reduction apparatus which reduces noise on the basis of the correlations between a current block and adjacent blocks of the picture data, on the one hand, and respective reference blocks of reference picture data, and on the basis of the non-correlation between the current picture data and the reference picture data, and a decoder having such a noise reduction apparatus. <IMAGE>
